“…In 2021, Hu et al. [51] developed a new CARPOM with high PV penetrations for distribution networks. This approach has reduced the “bus voltage fluctuations, active power curtailments of PV, distribution network operating losses, and adjustments of conventional voltage regulation devices such as OLTCs and CBs”.…”

Recently, there is vast progress in the integration of renewable energy generators (REGs) into the power grid. The reactive power, which is indeed a fundamental power system factor is being influenced highly by the renewable power penetration levels. As a consequence, this has paved the way toward the generation of steady-state voltage and dynamic/transient stability issues. Therefore, to provide a sustainable and dependable power grid, it is indeed important to maintain and control adequate reactive power reserves. This study introduces a comprehensive literature survey on "management of reactive power in renewable-rich power networks". A total of 75 research publications have been collected for this study, and a concise summary of each article is offered. The articles are categorized according to the types of REGs used, type of control, grid code consideration, controller device, implementation tools, grid type, load type as well as various reactive power support systems. In addition, this study examines the advantages and drawbacks of existing models. The performance recorded in each of the collected papers are discussed. Ultimately, the most critical challenges related to management of reactive power in renewable-rich power grids are identified, along with some essential methodological suggestions for the electricity sector, regulators, and research scientists.

“…It is not sufficient to establish a unilateral active-or reactive-power dispatching model based on the traditional active-and reactive-power decoupling theory. The reactive-power resources about the high proportion of PV will affect the network loss and voltage quality (Antoniadou-Plytaria et al, 2017;Hu et al, 2022). Active power optimization can reduce generation costs, and reactive power regulation can reduce network losses, together achieving the goal of minimizing operating costs.…”

With a high proportion of photovoltaic (PV) connected to the active distribution network (ADN), the correlation and uncertainty of the PV output will significantly affect the grid dispatching operation. Therefore, this paper proposes a novel robust ADN dispatching model, which considers the dynamic spatial correlation and power uncertainty of PV. First, the dynamic spatial correlation of PV output is innovatively modeled by dynamic conditional correlation (DCC) generalized autoregressive conditional heteroskedasticity (DCC-GARCH) model. DCC can accurately represent and forecast the spatial correlation of the PV output and reflect its time-varying characteristics. Second, a time-varying ellipsoidal uncertainty set constructed using the DCC, is introduced to bound the uncertainty of the PV outputs. Subsequently, the original mixed integer linear programming (MILP) model is transformed into the mixed integer robust programming (MIRP) model to realize robust optimal ADN dispatching. Finally, a numerical example is provided to demonstrate the effectiveness of the proposed method.

“…Similarly, in [9] the effectiveness of reactive power injection is presented and thereby the ability of large-scale PV systems to contribute to a stable grid condition is shown. In [10] Hu et al also conclude that higher PV integration is enabled if active and reactive power are applied in terms of voltage regulation. Another factor increasing flexibility while gaining grid stability is the integration of battery energy storage systems.…”

The rise of photovoltaic (PV) penetration is contributing to the increasing incidence of overvoltage detection in the electrical grid during times of high-power generation. Overvoltage can cause disturbances or (partial) failures in the electrical supply network, since the components used are designed for a certain voltage band. One option to counteract too high voltage levels and thus ensure power quality, grid stability and resilience is the absorption of active power by means of a battery energy storage system (BESS). In this paper, we first built a suitable simulation setup for a typical European network section, including a large-scale PV system connected to the 10 kV level and a BESS model. A suitable charging and discharging algorithm for the BESS with the aim to realize peak shaving for the grid voltage was developed and implemented. Simulations, performed in MATLAB/Simulink®, show the dependence of the battery capacity and power on the grid-serving effect of BESS. By determining appropriate values for these two factors a significant reduction of the voltage level could be achieved.
